WorkoutSpot 4+

WorkoutSpot allows you to analyze any point or segment of your workouts. Select a workout that you already have in Health. Add a workout to Health with the Workouts app on Apple Watch, or any app that Works with Health. 

Zoom into segments to see how long it took you climb that hill, or sprint between stoplights. The preview graph at the bottom of the screen, and the map at the top of the screen, help you see where in the workout you're currently looking at. 
Switch between time and distance domains while maintaining your current selection.

Select a point on the graph to view the details of that spot in the workout: 
- location on the map
- time of day
- distance
- altitude
- grade (terrain slope)
- speed
- heart rate

Select a segment by zooming and panning the graph to view details:
- highlight on the map
- duration
- distance
- climbed (ascent)
- average grade
- average speed
- average heart rate
